I'll get some quotes tomorrow to see how much it would cost. I had a go at it this evening, and made progress; I managed to drill out the least problematic bolt and get it threaded again, so there's now 1 bolt holding the cable bracket in place. This is also the second time I've heard the term galling in reference to bolts. I'll have to google it as I don't know what it means. Except that this whole experience has been galling..
Similar problem myself last week with my 61k salt encrusted mill. I have now decided to remove the exup valve after long deliberation hoping that the Ivanised carbs will equalise any mid and low range bogging. As far as removal of the header pipes, first appearances were displaying a range of different size unrecognisable well corroded nuts......... my solution was to borrow my son's Dremel and diagonally cut each nut to the studs thread and with a mangled old bent long screwdriver gently tap and split the nuts off, couple off hours job done. The headers are still solidly corroded into the Head with no sign of movement, next decision made, leave well alone, a new set of shouldered M8 nuts on the way and until there is any real reason to remove the Headers they can stay where they are . :b
